Full selection to prevent risks

The manual alarm siren plays a key role in protecting people. In the event of extraordinary events or threats, the warning siren is ideal for alerting people, especially when the site has no energy source. It is particularly suitable in campsites, schools, civil defence, but also for military defences, mountain rescue and coastal alerts.

To benefit from optimal safety on various projects and areas without electricity, the use of a manual siren that meets ATEX standards is essential. At Advanced Safety Solutions, you’ll find what you need, no matter what your sound alarm needs! The fact sheets are available online and offer you several practical information on all our references. By acquiring a manual siren, you choose to provide an effective warning for applications where there are no power supplies.


The strengths of manual sirens

Manual sirens have many advantages, especially for industries that require POI, PPI, PPMS plans.

The manual siren allows you to alert staff in case of danger, especially in areas without electricity. Indeed, no source of energy is needed to use it. In addition, its sound power allows a universally known alarm to be broadcast on large industrial sites, such as quarries or mines. Thanks to its shutter mechanism, the sirens we offer can provide more than three different warning signals.

Depending on the use and industry, opt for the LK-100 manual siren ideal for easy transport or the LK-100A for fast, solid mounting on a base. The LK-120 and LK120-A warning sirens with steel feet will be perfect for use at man-height.

Note that all our manual sirens are robust and compact for flexible use on your site.
